It would be great to have this cleaned up, by the City if necessary.

Why the City? Is this Yale's property? The City doesn't even clean its own stuff up.

Frats are private; they're not owned by the university. But there must be some City ordinance they're supposed to observe. Yesterday evening trash at least had been placed in a dumpster (whether it will ever be emptied is another question). Like the original poster, I hope an eye is kept on this address. The weekend of commencement isn't the only time during the calendar year that they should pay attention to upkeep of the property.

Well--this site was (briefly) cleaned up. Last night it was as bad as ever. A full and now torn-up black plastic garbage bag is lying on the ground, contents strewn all over--behind the fence that keeps the house from having to seeing it, but out in public and spilling over the sidewalk.

Thanks for reporting, will continue to monitor
